A modified method for isolating mouse islets of an adequate quality, quantity, and purity

Abstract

Mouse islets are widely used in diabetes research. Thus an adequate quality, quantity, and purity of islets are needed for high-quality investigations. We performed a combination of filtration and density gradient separation and optimized many steps in the islet isolation procedure, including perfusion, digestion, and purification. Our results show that an increased quality, quantity, and purity of isolated islets can be achieved using these modifications. Moreover, this method can guarantee maximal recovery and purity of the isolated islets and is easy to perform with practice.
